As a specialist for prototypes and small series, we manufacture high quality Injection Molds in China, 3D-Printing, Rapid Prototyping, CNC-Prototyping in China, Plastic Products. , Plastic Moulding and Die-Casting in China. The following list represents the most frequently asked questions of our customers:
What is Rapid Prototyping?
Rapid Prototyping is a manufacturing technology that quickly builds a prototype part. Many different technologies are available that are considered Rapid Prototyping, and many can also be used for production manufacturing. Although most Rapid Prototyping systems use a form of layered additive manufacturing, they can also use a variety of other methods such as high-speed machining, molding, casting, and extruding.
Rapid Prototyping is rapid prototyping when the entire process of going from a computer design to a physical model is faster than more traditional manufacturing technologies.
What is Rapid Tooling and how is it Different from Rapid Prototyping?
The only difference between Rapid Tooling and Rapid Manufacturing is the end use of the parts produced with the process. Both use rapid prototyping technologies to quickly make a part. But for Rapid Tooling, the part is used in another manufacturing process as a tool.
How should I select which Rapid Prototyping process to use?
The best way is to define the intended use of the prototype. As a general rule, Normally CNC prototype is a better choice.
What is 3D Printing and how is it Different from Rapid Prototyping?
3D Printing refers to a subset of rapid prototyping that goes directly from a 3D computer model to a prototype with very little user interaction other than defining some preferences. The process is designed to be as easy as printing from a computer to paper.
In many ways the name is a marketing label to clearly emphasize the affordability and ease of making prototypes using systems that are labeled as 3D Printers. It is also meant to appeal to a larger, less engineering and manufacturing oriented audience.
When and how is Rapid Prototyping used in Product Development?
Rapid prototyping can be used at almost every step in your product development process. At any point where you need a physical part you can benefit from Rapid Prototyping. Examples are:
Conceptualization: concept models, marketing mockups
Initial Design: form, fit, and function testing, visualization
Detail Design: testing, test fixtures, assembly testing, fit, form and function testing.
Production: tooling, mockups for process planning
Can I use Rapid Prototyping to make tooling for Injection Molding?
Yes you can. A special process and special materials are required, as is a special mold base. But a low volume injection mold can be made using Rapid Prototyping. PADT can also help find a supplier that can use rapid machining to make molds almost as fast as rapid prototyping.
What is FDM?
FDM is also known as Fused Deposition Modeling is layered manufacturing process. FDM offers functional prototypes with ABS, and other materials. A thin bead of molten plastic is extruded through the computer controlled nozzle, which is deposited on a layer-by-layer basis to construct a prototype directly from 3D CAD data. The technology is commonly applied to form, fit and function analysis and concept visualisation. In addition, FDM can be used for pattern generation and rapid manufacturing
Can you make functional prototypes?
It really depends upon the functionality of the product you want to achieve. We have various technologies available, to make functional parts e.g. FDM & SLS and CNC machining direct on industrial materials. Please check specifications and applications of different materials. Sometimes we machine prototypes from solid block of metal or plastic block to get the maximum strength when demanded.
Why would I want a urethane casting?
Urethane casting can make sense when your project requires a high number of models or when the properties of the SLA materials may not meet the requirements of your particular application.
What is RTV tooling?
A. RTV means Room Temperature Vulcanization. It refers to a rubber material that will completely cure at room temperature. By encapsulating your part in silicone, we can create a rubber mold that will allow us to make a number of copies of the part using, in most cases, a polyurethane.
What is RTV Urethane Molds?
RTV (Room Temperature Vulcanization) silicone molding is a well-recognized rapid tooling method for producing small quantities of production-like prototypes of plastic injection molded parts. Short mold lead times are coupled with exceptional detail and surface finish. Complex parts with undercuts can be produced using this process. RTV molding is very cost effective at low quantities while maintaining good accuracy and excellent detail. Prototype parts can be color matched and textured with a variety of material characteristics. Durometers range from very soft foams or rubbers through very rigid nylon-like materials. Some functional testing can be performed.
How Does RTV Work?
The RTV mold is created from a master pattern, typically an RP model. The pattern is used to create a silicone rubber mold. The silicone is poured around the pattern to produce a core and cavity of a mold. The RP model is then removed, leaving a negative image into which polyurethane is cast. These molds can produce up to 20 parts per mold, and they can be made as family or multi-cavity molds.
When is RTV Molding useful for rapid prototyping?
RTV is very helpful when you need a spec-like material for multiple sets, in a short timeframe, for less than a traditional tool would cost.
How does Reaction Injection Molding (RIM Molding) Work ?
Reaction Injection Molding (RIM) is the process by which molded polyurethane parts are made. In the process, 2 liquid components are mixed and injected into the mold where they chemically react and cure.
Polyurethane molded parts can be rigid and solid like an injection molded ABS or they can be a structural foam or elastomeric like rubber.
Two liquid reactants – polyisocyanate component and resin mixture – are held in separate temperature controlled feed tanks equipped with agitators. From these tanks, the polyol and isocyanate are fed through supply lines to metering units that precisely meter the reactants, as high pressure, to the mixhead. When injection begins and valves in the mixhead open, the liquid reactants enter a chamber in the mixhead at pressures between 1,500 and 3,000 psi where they are intensively mixed by high-velocity impingement. From the mix chamber, the liquid flows into the mold at approximately atmospheric pressure and undergoes an exothermic chemical reaction, forming the polyurethane polymer in the mold. Shot and cycle times vary, depending on the part size and the polyurethane system used. An average mold for an elastomeric part may be filled in one second or less and be ready for demolding in 30- 60 seconds. Special extended geltime polyurethane RIM systems allow the processor to fill very large molds using equipment originally designed for molds with smaller volumes.

What is Reaction Injection Molding (RIM)?
Low Quantity Injection Molding For Life Sciences Industry
The Reaction Injection Molding (RIM) process economically produces low quantity injection molded parts for the Life Sciences industry. Medium to large enclosures and housings can be produced in low quantities from low-cost tooling. Designing for the RIM process is easier than designing injection molded parts because the RIM process allows much more design freedom.
The RIM process is relatively new and perhaps the least understood, most under utilized of the low-pressure processes for plastic parts. Recent developments in resins have allowed this high-value process to compete with injection molding. Thin wall parts that meet UL flame requirements can be produced with faster cycle times. Plastics experts call RIM “the low-pressure process that comes closest to duplicating injection molding’s attributes. It has impressive large-part, small quantity and low initial investment capabilities.”
OEM’s in the Life Sciences industry are using RIM instead of injection molding, vacuum forming, pressure forming, structural foam, sheet metal, or metal casting. RIMs lower cost tooling allows them to get their products to market faster and to change them more.
How many parts can you produce from one silicone mold?
The answer to this question is highly dependent on part geometry and choice of material, but typically you can expect a single rubber mold to yield about 25 parts.
What tolerances can you hold?
Typical tolerances on our SLA models are about +/- 0.005″. For parts over 5″ we can hold around +/- 0.001″ to 0.0015″ per inch. Part geometry and build orientation can also have an effect on tolerances.
